OT: Chemical Etching on glass

So I told my insurance carrier that I had a better deal from another
company and they miraculously found a better rate for me for the same
coverage. However, when the policy came it said I needed proof that
my VIN had been etched into all of my car windows. This wasn't the
case, but I googled it and bought a kit for $25 on eBay. Simple
process - they send you stickers with your VIN printed in it, you put
them on your windows and then rub etching cream over the numbers.
(It's a stencil, not a sticker I guess.) Worked like a charm. I'm
thinking of trying to etch my own steel tools and maybe even a logo
into metal to apply to my work. Just an FYI if you want to see if you
can reduce your car insurance rates.

Since hydrofloric acid is the only acid I know of that attacks glass

(Thank heavens), just wonder what the active ingredient is?

Forgive me for being paranoid, but if it etches glass, can it be good for
you or your teeth?

The point is, in order for a thief to sell on a stolen car, requires that
its existing identity be hidden. If the VIN is etched on all the glass it
is not easily removable and visible to any would be buyer. To replace all
the glass in a car is expensive so not worth the effort to a thief.

Doesn't stop a thief stripping your car and selling the parts for spares
though >-|

Melt is right - it also dissolves the bone joints!!

It is absorbed through the skin. So be careful.

We used it in the semiconductor business - to dissolve layers of IC's.
It is really nasty stuff - most of the stuff on earth it dissolves!

That Etch-O-Matic Looks Pretty Cool, but Not Nearly as Cool as the Random
Capitalizer-O-Matic They Used On The Text in the Description of The Product.

You have car window thefts where you live?

Most are a mixture w/ ammonium bifluoride.

Look up MSDS for any particular product.

If you know the brand name of the etchant, google that name and "MSDS"
and you may find a material safety data sheet that lists the
known-hazardous ingredients. Looking them up for a couple of commercial
etching creams revealed that they contained sodium fluoride (the same
stuff the dentist uses on your teeth) or ammonium fluoride or both.
Most fluorides will etch glass--you may even be able to do it with a
fluoride toothpaste but it might take a while for the etch to take.

Decades of clinical experience suggest that it is very good for your
teeth. But it can etch porcelain crowns and the like.

Swallow too much of it and it can hurt you but you have to swallow a lot
of it. And people who go on about how anything that is toxic in volume
is also toxic in small quantities need to consider that air is highly
toxic--causes intoxication, convulsions and death if you get too much of it.

Remember, hydrochloric acid will etch steel nicely, but your stomach
makes it to digest your food.

It all depends on the concentration applied and the total amount given.
As I remember Arsenic and Selenium both serious poison are essential
trace elements in the body.

Thiamine, a vitamin B, is good, but when you are covered in its dust
from head to foot for 8 hours per day it is bad.

Insurance companies have very strange policies. My home insurance
gave me a reduction for bolting window latches. I changed companies
and then removed the bolts, except the ones to my shop.
